Hmm, this still looks questionable. I would have expected the whitespace trimming to be below the 'defined' check but before the length($author)==0 check (since the length might become 0 once whitespace is trimmed).

Also, a minor style/comprehension nit: Perhaps I'm just old-school, but for me, the idiom:

    $author =~ s/^\s+//;
    $author =~ s/\s+$//;

is easier to understand at-a-glance as trimming leading and trailing whitespace than the more compact (noisy) expression this patch uses. But that's just a subjective review comment, not necessarily actionable.
